Long-term storage of three unconventional oils
Grasas y Aceites, 2008 Three samples, Sclerocarya birrea oil (SCO), Melon bug oil (Aspongubus viduatus) (MBO), and Sorghum bug oil (Agonoscelis pubescens) (SBO), were stored (autoxidized) in the dark at 30±2 °C for 24 months.

Journal of the American Oil Chemists' Society, Volume 102, Issue 8, Page 1185-1200, August 2025.ABSTRACT The quality and shelf life of extra virgin olive oil (EVOO) are pivotal to its marketability and consumer satisfaction. This study evaluated how pyropheophytin a (PPP) and 1,2‐diacylglycerols (DAGs) changed for different varieties of EVOO over a 24‐month storage period under varying temperature conditions (16°C, 18°C, and 20°C).

Comparison of rancimat evaluation modes to assess oxidative stability of fish oils
Journal of the American Oil Chemists' Society, 1997 AbstractTwo Rancimat evaluation modes, the induction period (IP), and the time needed to achieve a selected difference in conductivity (tΔK) were compared for assessing relative stability of anchovy, sardine, and hake liver oils. Mean coefficients of variation were 2.5 and 2.4% for IP and tΔK values, respectively, for oils oxidized in the range 55–90°C.

Plant Biotechnology Journal, Volume 23, Issue 8, Page 3451-3464, August 2025.Summary Ketocarotenoids, including astaxanthin, are red lipophilic pigments derived from the oxygenation of β‐carotene ionone rings. These carotenoids have exceptional antioxidant capacity and high commercial value as natural pigments, especially for aquaculture feedstocks to confer red flesh colour to salmon and shrimp.
